This document reports the tabulations of a national study sponsored by the Office of Child Development of the U.S. Department of Health, Education and Welfare to determine exactly how children are cared for, how often child care services are purchased, at what costs, for what reasons and with what accompanying problems or barriers. Of related interest are the preferences, opinions and attitudes of consumers.

The data are organized under the following headings: (1) Design and Methodology, (2) Characteristics of the Sample Households, (3) Measures of Child Care Usage, (4) Reasons, Satisfaction, Preferences and Prior Usage, (5) Cost and Transportation, (6) Opinions and Attitudes.
